To al whom it trtcgwancem; v

Be it known that 1, Epson (3.- Coveirr, a resident of'New Kensington, county ofVVe'stmoreland, and; State of Pennsylvania, have f Metallic Carl-ines',

being had to Which-form'pant l0 .for box and si1nilsr-.ca-rs,-'ai1dhasfor its invented ain'ewand useful- Improvement in of which the following is. a full, clear, and exact description, referencethe accompanying drawings,

of. this specification. TlIlIS' invention relates to=metallic cai'lines primary object the-provision of-a construc tlOIlWhlCh for the s'aineweight ofmaterial will give greater strengththanis present .111 this member as heretofore constructed:

Further objects are to provide a' strong,

light Weight carline having purl-in pockets of great width and to provide other details fully described.

The upwardly projecting portions of the gitudinal legs 9 which form the compression member ing flange or leg 8 forms the tension member.

The T-shape embodied in my improved carline is preferably the ordinary commercial or conventional rolled T-section. The shape may be purchased in the open market and is readily cut to the desired length and rolled or pressed to the desired shape, and

out heating, as desired.

my invention there is presented a construction able to meet the maximum root stresses with a minimum amount of material.

Having thus described my invention, WhFLlJ 1;, V

I claim and desire to secure by Letters Patent is:

1. A metallic carline, comprising a rolled section having a 'l -shaped cross section, and

leg thereof, defined by twisted deflections of such leg.

2. A metallic carline comprising a rolled section having a T-shapcd cross section and having separate portions of the opposite edges of its horizontal leg struck upwardly.

to form longitudinal ribs lying above the general plane of said leg, the intervening portions of the leg forming purlin pockets.

In testimony whereof, I have hereunto set my hand.
